• Wide variety of data backup installations and environments

The Dell DR Series system contains data backup and management software preinstalled on a Dell hardware appliance,

which provides you with a robust disk-based data backup capability installed on a deduplication-enabled appliance.

The system supports two interface types, and the system software manages the storage containers using the following

interfaces:

• A command line interface (CLI)

• A graphical user interface (GUI)

About the DR Series System

The Dell DR Series system is a solution designed to reduce your backup data footprint using a number of comprehensive

backup and deduplication operations that optimize storage savings. Collectively, the DR Series system comes in two

types:

• DR4000 system: this is preinstalled DR4000 system software on a Dell PowerEdge R510 appliance platform

• DR4100 system: this is preinstalled DR4000 system software on a Dell PowerEdge R720xd appliance platform

The DR Series system consists of the following components:

• Software — the system software supports record linkage and context-based lossless data compression

methods.

• Hardware — there are two appliance types that support the DR Series:

– DR4000 system: includes twelve 3.5 inch SAS or Nearline SAS chassis drives that are hot-swappable,

two power supplies for power redundancy, and two cabled 2.5-inch SAS drives for the operating

system. The operating system is installed on two 2.5–inch internal drives that are in a RAID 1

configuration in the DR4000 system.

– DR4100 system: includes twelve 3.5 inch SAS or Nearline SAS chassis drives that are hot-swappable,

two power supplies for power redundancy, and includes two 2.5-inch drives that are hot-pluggable in

the rear.

注: For slot locations for the twelve 3.5–inch drives in the DR Series system types, see DR Series System

and Data Operations.

• Expansion shelf—the system appliance supports the addition of up to two external Dell PowerVault MD1200

data storage expansion shelf enclosures. Adding an expansion shelf provides additional data storage for the DR

Series system and also requires a license. Each added expansion shelf enclosure must be equal to or greater

than each DR Series system internal drive slot capacity (0–11).

注: The 300 Gigabyte (GB) drive capacity (2.7TB) version of the DR Series system does not support the

addition of expansion shelf enclosures.

For more information, see Expansion Shelf Licenses. For more general information about the supported storage

enclosures, see “DR Series Expansion Shelf” in DR Series System and Data Operations, and
